BIPV/T for arctic residential applications

Abstract

This study aims to investigate the performance of an open loop air-based building integrated photovoltaic/thermal collector (BIPV/T) to preheat Energy Recovery Ventilator (ERV) supply air and to generate electrical energy. ERVs have proven successful in cold climates, but in the extreme cold of the arctic frequent frosting and defrosting cycles reduce their effectiveness and increase energy consumption. Thus, by integrating with BIPV/T, this problem can be reduced while also generating solar electricity. A finite difference model of the BIPV/T system integrated in a typical potential application was simulated in MATLAB using local weather data and fresh air requirements to obtain system outputs. BIPV/T parameters such as tilt angle, cavity width and height were varied, keeping in mind nominal lumber sizes and ease of construction for improved implementation for Arctic residential applications.
